Last Updated : 09 Sep, 2021

Introduction: jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxDropDownList widget is a jQuery drop-down list that contains a list of selectable items displayed in the drop-down list.

The valueMember property is used to set or return the valueMember of the Items. This property specifies the name of an object property to set as a ‘value’ of the list items. It accepts String type value and its default value is “”.

Syntax:

Set the valueMember property.

$('selector').jqxDropDownList({ valueMember: String });

Return the valueMember property.

var valueMember = $('selector').jqxDropDownList('valueMember');
